This tutorial shows a quick and easy way to create a coloured pencil effect from a black and white line drawing (originally a photo).
I had a couple of comments on a previous post asking how to change the finished black and white line drawing into a coloured line drawing. I will start the tutorial from where I left the previous post. If you are starting this tutorial afresh start at Step 2.
I am starting with a new image ‘Locomotive ChS4-072 2011 G1.jpg‘ by ‘George Chernilevsky‘ and have followed the steps in ‘How to change a photo into a pencil line drawing‘ to turn it into a black and white line drawing.
If you have just finished the previous tutorial, you should have your main picture as a line drawing and you will have 3 layers in the layers palette. Merge these layers – to do this select the 3 layers in the layers palette (Hold Apple / ctrl to select multiple layers) and select Apple E / ctrl E.
You should have your line drawing now on a single layer in the layers palette. Create a new layer (select the icon at the bottom of the layers palette to the left of the bin).
Move the new layer beneath the line drawing. Click and drag the layers in the layers palette to do this. (If the drawing layer is a background layer which is locked – double click this layer in the layers palette and choose ‘ok’ to unlock it).
Choose the paint bucket from the toolbar and choose the colour that you would like the line drawing to be in the colour palette.
Select the new layer you’ve created in the layers palette and fill the canvas with colour. (This layer is hidden behind the line drawing on top, so you will only see the change in the layers palette).
Select the line drawing layer and choose ‘screen’ from the drop down menu. Your line drawing will now taken on the colour of the layer beneath.
You can continue to change the colour of the line drawing and add more colours to the bottom layer.
Try using a multi gradient on the bottom layer to create a rainbow effect
